Audio-GD Precision 3 2020 Edition

Balanced Class A Amplifier ACSS 2x 70W 8 Ohm

Audio-GD is upgrading its Audio-GD Precision 3 by offering this 2020 edition. It is based on the previous model, but with a modified circuitry and adjusted sound performance to offer an even more transparent reproduction.

The Precision 3 2020 Edition therefore offers a 100% discrete architecture, capable of delivering a power of 2x70W under 8Ω or 2x15W under 40Ω (for headphones). Its input stage is in Class A, without feedback on the ACSS input with DC coupling of the analog amplifier.

The gain and pre-buffer stages also operate in Class A, with discrete analog stages, without AOPs or coupling capacitors in the signal path. The "Diamond Cross" type output stage with no feedback avoids crossover distortion, thus competing with Class A amplifiers.

  • 4 transistors of 150W 15A each.
  • Oversized power supply with 40 000µF Nover filtering.
  • High precision KOA 0.1% resistors and WIMA capacitors.
  • Isolated power / amplification section to limit electromagnetic radiation.

The Precision 3 2020 Edition takes advantage of the latest ACSS technology, enhancing RCA connections to approach the quality of ACSS connections. It has a single voltage gain stage for signal processing, but operates entirely in ACSS mode, which is actually a current gain stage. This design allows the signal path to be significantly shortened, for a more neutral and faithful sound.

A refined and efficient connection system

The Audio-GD Precision 3 2020 Edition has 2 analog inputs: an RCA input and an ACSS input. The output is of course done on 2 speaker terminals accepting banana plugs. The result is simple: great musicality, thanks to exceptional dynamics and a rich sound that is extremely detailed in every detail.

Mono Bridge Mode XLR to RCA or ACSS

The mono bridge mode of the Precision 3 2020 Edition allows the output of no less than 200W per unit. For this, a preamplifier with conventional balanced XLR outputs or a DAC Audio-GD preamplifier from the NFB series is absolutely necessary. All you have to do is connect your speakers to enjoy them, following the diagram below. However, you will need to use Audio-GD proprietary modulation cables (available as accessories).

It is also possible to bi-amplify the output of a DAC Audio-GD NFB preamplifier in ACSS or RCA, via a conventional preamplifier. The cable required for these setups is available as an accessory.
